Article Synopsis
- The study aimed to compare the effects of 8 mm and 9 mm optical zone diameters on correcting corneal astigmatism during cataract surgery with femtosecond laser corneal relaxing incisions (CRIs).
- Results showed that the 8 mm optical zone significantly reduced postoperative corneal astigmatism (0.77 D) more than the 9 mm zone (0.42 D) and had better outcomes in terms of correction index and astigmatism control.
- The 9 mm group had deeper incisions (79.30%) compared to the 8 mm group (72.58%), indicating that shallower incisions in the 8 mm group were
Aim: To investigate the efficacy of a new visual acuity (VA) screening method, the baby vision test for young children.
Methods: A total 105 eyes of 65 children aged 2-8y were included in the study. Acuity testing was conducted using a standardized recognition acuity chart (Snellen visual chart: at 3 m) and the baby vision model assessment.

Article Synopsis
- The study aimed to compare the rotational stability of two types of toric intraocular lenses (IOLs) during cataract surgery in patients with preexisting astigmatism.
- Results showed that the AcrySof IQ (SN6AT) IOL exhibited significantly better rotational stability compared to the TECNIS (ZCT/ZMT) IOL across all follow-up intervals.
- The delay in capsular bend formation in the TECNIS group, along with fibrosis in the anterior capsule, contributed to its poorer performance in maintaining stability compared to the AcrySof IQ group.
Introduction: During phacoemulsification, the infusion pressure can cause the liquefied vitreous fluid to escape through the ciliary fiber interspace in highly myopic eyes, leading to reduced vitreous cavity pressure similar to vitrectomized eyes. This study assessed the probability of low intraocular pressure (IOP) in high myopic eyes with different axial length (AL) group undergoing cataract surgery, as well as the impact of balanced salt solution (BSS) supplementation and the optimal IOP value for such supplementation.
Methods: The control group consisted of cataract eyes with normal AL (group 1: 22 mm ≤ AL < 24.
Introduction: This study analyzed the visual outcome following cataract surgery with toric intraocular lenses (IOLs) in patients older than 80 years with corneal astigmatism.
Methods: A total of 159 patients (159 eyes) older than 80 years with corneal astigmatism (≥ 0.75 D) were included.
